It's not a good idea to plant crassula until after all chance of frost has passed because they do not do well in cold weather.

The earliest that you can plant crassula in Louisville is April. However, you really should wait until May if you don't want to take any chances.

The last month that you can plant crassula and expect a good harvest is probably August. Any later than that and your crassula may not have a chance to really do well. If you are starting your crassula indoors then you might be able to get away with starting them a little bit earlier.
